I'm on my climb up to max, probably 4 months or so off it and I recently maxed my zookas. Took advice off my friend who used tmed to steamroll and it helped leveling up, now I want to focus on operations and more strategy (little late, we all start from somewhere).
I've notice with smokey zooka attacks that critters are way more useful than I ever knew. What I don't understand is why shock them? Yes it holds them in place for things to attack, though can't you put them down to distract, then shock other defences while the initial ones are attacking the critters?
This obviously depends on layout, you would shock if a flamethrower or mortar is in the way, though I'm just asking on a general basis. Does it keep the critters alive longer so things you can't shock keep killing them while the shocked defences are... well... shocked?
